Alba Cornelio, 39, and Carla Cornelio, 20, already pleaded not guilty to felony and misdemeanor charges related to the mauling. They were arraigned on the new charges Wednesday in San Diego Superior Court.

They face up to four years and eight months in prison if convicted.

Prosecutors said the pit bulls attacked Emako Mendoza, then 75, in her backyard on Alleghany Street on June 18. The dogs pushed through a gap between two fences that separated the Cornelio’s property from Mendoza’s home.
